PHINEAS Il'. ADAMS, JR., AND ORSEMAS T. X. ADAMS, OF CHICAGO, ILLINOIS,

ASSIGNORS TO IMIELINDA PECK, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 399,124, dated March 5, 1889.

Application filed January 3, 1889.

To all whom, t muy concern:

Be it known that we, PHINEAS ll. ADAMS, J r., and ORsEMAs T. X. ADAMS, citizens of the United States, residing at Chicago, Illinois, have invented a certain new and useful Plant for Ilse in Smelting Orcs, of which the following is a specification.

The object of our invention is to arrange a plant for use in smelting ores and centrifugally treatin g the resulting materials and me chanically decomposing' chemical compounds, metallic salts orsalts of metals, and desulphurizing ores or their resulting material as they 'flow from the smelting-furnace, when the suby stances treated are in a molten condition, by the act-ion of centrifugal force; and our inA 1 vention consists in the ai'rangcment and combination of the various features hereinafter described and claimed.

In the drawings, Figure l is a plan view of a number of smelting-furnaces with our ccntrifugal apparatus in place. Fig. 2 is a section on the line 2 2 of Fig. l, showing the lower part of one of the smelting-furnaces and one of the centrifugal apparatuses in elevation, the apparatus being located in an eX- cavation. Fig. 3 is a cross-section of one of the troughs or pipes for conveying the molten material from the smelting-furnace to the centrifugal apparatus, taken in the line 3 of Fig. l, looking in the direction of the arrow; and Fig. l is a side elevation of the lower part of a smelting-furnace, a horizontal centrifugal apparatus, and a precipitating receptacle arranged between the two.

In arranging our plant for use in smelting ores and centrifugally treating the result-ing materials and mechanically decomposing their chemical compounds, metallic salts or salts of metals, and desulphurizing ores or :y their resulting materials as they iiow from f the smelting-furnaces, and while the substances treated are in a molten condition, by i the action of centrifugal force, we prefer to l arrange the smelting furnace or furnaces and the centrifugal apparatus or apparatuses in such relation to each other that the material to be treated may be conveyed directly and by gravity from the smeltingfurnaces to the apparatus in which it is treated. To this end Serial No. 295,370. (No model.)

` we prefer to arrange several'smelting-furnaccs, preferably in close proximity to each other, and in a line or row, and to arrange a number of centrifugal apparatuses in proximity to cach other and to the smclting-fur- 11a-ces, and preferably in a row on the same side of the smelting-furnaces.

lVe do not propose in this paient to claim any special construction ol sm ltingfurnace, nor any special construction of centrifugal apparatus. lY'e contemplate the use of different kinds of siuelting-furnaces aud of different kinds of ccntrifugz'll apparatuses, whether arranged vertically or horizontally.

' le need not therefore enter into the details of construction of either the furnaces or the centrifugal apparatuses, but shall proceed to describe the adaptation of cach to the other to secure the results desired in thc mostconvenient and economical manner.

After arranging a number of smeltiug-furnaces, A, intended to cuter into the plant in .their respective positions, and, as before said, preferably in a row, we arrange one or more centrifugal apparatuses, B, close to them, preferably in a row, where more than one are used, and preferably in a trench or excavation, C, so as to bring them into such relative height to the smelting-furnaces that the material in a molten state may flow directly from the furnaces to the apparatus. The trench or excavation in which the centrifugal apparatuses are arranged should be of sufficient size to permit access to the apparatus and, if desired, the introduction of a car or other means along a passage, J, for conveying away the material discharged by centrifugal force from the receiving-vessel ol the appara-tus.

Although we have shown the centrifugal apparatuses as extending slightly above the surface of the ground, we would recommend that they be arranged low 'enough down to permit the trench or excavation in which they are located to be covered, so as to present a uniform surface; but the trench or excavation should be covered by a iioor or cover, E, whether the tops of the centrifugal apparatus extend above the surface of the ground or not, as it is important to provide a level even surface before the furnaces for conducting IOO ferent figures of the drawings.

operations. \Ve also prefer to provide the trench or excavation with extensions or conduits F, along which the belts or shafts for transmitting power to rot-ate the actuating- 5 shafts of the centrifugal apparatus maybe conveyed.

Of course it will be understood that the power for rotating the actuating-shafts will.

be provided by the use of a steam-engine,

1 o water-power, or other convenient means, which zo illustrated in Fig. 1 of the drawings. In liig.

3 we have shown a cross-section of the pipe or spout, where we have shown it with spaces in its walls to prevent the radiation of heat; but however the pipes or spouts may be made, we prefer to provide them with a cover, so that the material Iiowing from the smelting-furnaces will be maintained at as great a heat as possible, so as to preserve its Iiuidity. Te also prefer to use a precipitating-receiver, H, as shown in Fig. 4 and in dotted lilies in Fig. l. The object of this precipitating-receiver is to afford means to permit the heavier particles of the material, which will readily precipitate, to settle and 3 5 be caught without passing them into the centrifugal apparatus. This precipitating-receiver,'-however, may be dispensed with and all of the material carried into the centrifugal apparatus, if preferred, or it may form the 4o sole conduit between the smelting-furnaces and the receiving-vessels, dispensing with pipes or spouts. If used, however, it may be provided with a spout or tap-hole, l, to enable the material settling in it to be drawn ol'f from time to time, as desired.

In operation the ores or metals, of whatever kind they may be, are smelted or reduced to a molten condition in the smelting-furnaces in the usual way. lhen thus reduced to a 5o condition of iiuidity, the material is conveyed from the sinelting-furnaoes into the centrifugal apparatus. The receiving-vessels of the centrifugal apparatuses are rotated at a very high rate of speedpreferably several thousand revolutions a minute-which causes the heavier particles in the material treated to pass to the outside, where they are retained, and the lighter particles to the center ot' the rotating receiving-vessels, whence they are 6o discharged by the action Oi' centrifugal force.

After the lighter particles of the material have been discharged from the receiving-vessels they are caught in any convenient way and flowed or conveyed into the cars or recep- 6 5 tacles provided for their removal, whence they are taken from time to time and dumped or l.
